Appunti ma :ma 2s,

The object of the resent invention is to provide a structure o a novelcharacter that will -not scratch the glass of a windshield, will providea better vclamp for the Wi` er strips, and lwill produce a cushionedbearing for the loose or free'portions thereof that will lessen thecracking and breaking of said A strips. L

In the accompanying drawmgs: j Figure 1 isa side elevation of a wiperconstructed in accordance with the present invention. f

Figure 2 is a. the same. v

Figure 3 is a cross-sectional view of a Sli h tly modified form ofconstruction.

onsidering first -the embodiment dlsclosed .in Figures 1 and 2, achanneled holder of metal is employed, preferably formed by bending asheet to form side walls 4. This metal body is embedded in an outercasing of rubber or other material' of an analogous character,designated 5. The wiper strips are shown at 6 and are clamped in vplacey and between the walls 4 of the metal body,

but are in actual contact with the softer materialj 5. The stripsproject beyond the body and material, as shown at 7 to formthe usualwiping flaps. A- carrier rod 8 is shown and 0 is provided with la yoke 9that embraces the 'structure inthe usual manner and -is secured theretoby a boltl 10. This yoke and the fascro'ss sectional view through tenerare surrounded by ribs 11 formedof the material of the casing `With thisstructure, it will be evident that' no metal will engage the glass Ofthe windshield as the wiper is caused to traverse the same even thoughthere is suicient 1play in the parts to permit the body to strike t elass ause the metal parts are all enclosed and arded bythe material 5.Said material rthermore produces a better 'clamping sur- Afacefor thestrips 7 and as said strips bend against the material the danger oftheir being cut and broken .is materiell lessened'.

A modification of the a ve' structure -is bea L may walls thereof, and'aratefrom the guard and from the ma; serial no. 264,146.

shown in Figure 3, wherein the channeled metal body is designated 4 andthe fr ee edges and mar ins only are surrounded b the rubber-1i e guardand clamping material 5B. e wiping strips are shown at 6'* and areclamped between said marginal protector 5*. AFrom the foregoing, it isthought that the construction, operatlon and many advantages of theherein described inventionwill 'parent to those skilled in the art,without urther description and it will be under- A stood that variouschanges` in the size,shape,

proportion and minor details of construction be'resorted to withoutdeparting from `the spirit or sacrificing any of the advantages of theinvention. t

What I claim, is

1. A wiper comprising a channeled holder, a guard of softer substancethan the holder covering the margins thereof, and a flexible wlping bodyseparate from the guard and jclam ed between the member. Y 2. A wipercomprising a channeled holder, a guard of softer substance than theholder covering the inner and outer sides of the same and enclosing thefree edges of the side a flexible wiping body sepclamped between thewalls of the channelmember, said body projecting beyond the channelmember.

3. A wiper comprising a channeled holder, a guardof softer substancethan the holder covering .the 4inner and outer sides of the same and.enclosing 'the free ed walls thereof, a flexible wiping guard materialand tween, the walls of the channel ody separate member, said bodyprojecting beyond the channel member, and a carrier arm having a yokeembracing and secured -to the holder, said guard having ribs surroundingthe yoke and projecting beyond the sides'of the same.
